Dahe is the drafting company of the Chinese Industry Standard：YB/T4001<Steel bar grating>.

大和自1993年开始生产钢格板，如今拥有2条压焊生产线，可生产负载扁钢由20X3mm至100X10mm：横杆间距由20mm到100mm的各种规格的压焊钢格板，年产压焊钢格板达20000吨。

Dahe have started producing Steel Grating since 1993. Now we own two production lines for Pressure-Welded Grating, which can produce all kinds of Pressure-Welded Grating that the bearing bars size are available from 20x3mm to 100x10mm and cross bars space are available from 20mm to 100mm. The annual production capacity of Pressure-Welded Grating is 20000 tons.

大和生产的小横杆间距的压焊钢格板(横杆间距20mm)，从根本上解决了钢格板操作平台存在着空中坠落物引起的危险的问题，从而解决了操作平台的安全与造价之间的矛盾。

Dahe produce Pressure-Welded Grating with small space of cross bars(c/c 20mm), which can solve the problem of risk from air falling as well as the inconsistency between the safety and the cost at all.

大和生产的安全平台钢格板和无障碍通道钢格板，特别人性化，以安全性作为第一思考，落实以人为本的传统道德，在现代工业，市政，公共建筑中的和谐体现，是现代社会的进步。
